在PHP中使用CURL访问页面：

<?php

$ch = curl_init('http://www.baidu.com'); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
// 3. 执行并获取HTML文档内容
$output = curl_exec($ch);
// 4. 释放curl句柄
curl_close($ch);
echo $output;
?>

Copy after login

可以显示页面，并且可以使用curl_getinfo函数获取请求头。

但不能直观的查看，而且无法使用Fiddler进行抓包。

经过搜索后终于找到解决办法：

Fiddler的抓包方式：打开Fiddler后，自动设置浏览器代理到127.0.0.1:8888。

所有浏览的网页均通过该端口进行转发，固可以抓包。

修改PHP代码：

<?php

$ch = curl_init('http://www.baidu.com'); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch,CURLOPT_PROXY,'127.0.0.1:8888');//设置代理服务器 
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);//若PHP编译时不带openssl则需要此行 
// 3. 执行并获取HTML文档内容
$output = curl_exec($ch);
// 4. 释放curl句柄
curl_close($ch);
echo $output;
?>

Copy after login

发现返回：

抓包信息为：

经过分析后发现，请求域名，必须以“/”结尾。

更改后代码

</span><span style="color: #0000ff;">echo</span> <span style="color: #800080;">$output</span><span style="color: #000000;">;
</span>?>
